Bynea (/ˈbɪnjə/ BIN-yə) is a village close to the River Loughor in Carmarthenshire, Wales. It also forms a electoral ward for the purposes of elections to Carmarthenshire County Council.
This was an agricultural area until the turn of the twentieth century, when it became heavily industralised with coal mines and steelworks. Bynea runs into the village of Llwynhendy, and between the two there are four places of worship, and a number of pubs.
Terry Davies, the rugby union player, is from this area and Kel Coslett the Rugby League legend was born there.
The village is served by Bynea railway station with trains operating to Swansea to the south and Shrewsbury to the north.
